.get_ott_lineage        Get the lineage of a set of taxa.
                        '.get_ott_lineage' uses
                        'rotl::taxonomy_taxon_info()' with
                        'include_lineage = TRUE'.

                        Gets classification paths for a vector of taxa
clean_ott_chronogram    Clean up some issues with Open Tree of Life
                        chronograms For now it 1) checks unmapped taxa
                        and maps them with tnrs_match.phylo, 2) roots
                        the chronogram if unrooted
clean_taxon_info_children
                        Identify, extract and clean taxonomic children
                        names from a 'taxonomy_taxon_info()' output.
clean_tnrs              Eliminates unmatched (NAs) and invalid taxa
                        from a 'rotl::tnrs_match_names()' or
                        'tnrs_match()' output. Useful to get ott ids to
                        retrieve an induced synthetic Open Tree of
                        Life. Needed because using 'include_suppressed
                        = FALSE' in 'rotl::tnrs_match_names()' does not
                        drop all invalid taxa.

get_ott_children        Use this instead of 'rotl::tol_subtree()' when
                        taxa are not in synthesis tree and you still
                        need to get all species or an induced OpenTree
                        subtree
get_ott_clade           Get the Open Tree of Life Taxonomic identifiers
                        (OTT ids) and name of one or several given
                        taxonomic ranks from one or more input taxa.
get_ott_lineage         Get the Open Tree of Life Taxonomic identifier
                        (OTT id) and name of all lineages from one or
                        more input taxa.
get_valid_children      Extract valid children from given taxonomic
                        name(s) or Open Tree of Life Taxonomic
                        identifiers (OTT ids) from a taxonomic source.
is_good_chronogram      Check if a tree is a valid chronogram.
